Remove the front panel assembly.

If you experience "ghost" or "phantom" touch input issues with your new display, this can be resolved by adding a layer of very thin insulating tape, such as Kapton (polyimide) tape, to the highlighted areas on the back of the panel. iFixit panels come with the proper insulation, and should not require the addition of any tape.

Without the proper insulation, these areas of the digitizer can ground out against other components, causing touch input malfunction.

The insulation is not visible to the naked eye, and is different from the foam dust barrier strips found on many iPads.
